FFAStrans is an unattended Windows tool aimed at broadcasters and video professionals for automatic transcoding of media files through drop folders. It's based on FFMpeg and relies on AviSynth for filters. Also it's one of the few free tools which supports multiple watch folder with separate transcoding configurations. It's best compared with the likes of Telestreams Episode and Vantage, Harmonics ProCoder, Digital Rapids Transcode Manager, Adobe Media Encoder, Amberfin iCR etc. FFAStrans is targeted at those with lots of different media formats coming from lots of different places and wants the transcoding process done automatically. FFAStrans is created by Steinar Apalnes.

Version history / Release notes / Changelog

What's new in version 1.1.0?


New encoder: XAVC (Sony style AVC Intra). Currently only i-frame up to 1080p60 class 200 properly supported.
New encoder: Generic MPEG1/2.
New analyzer: Video metrics. Compare video quality using VMAF, SSIM and PSNR.
Much improved internal priority control:
"Max active jobs" are now per priority setting. Meaning if you have used all your job slots on lower priority jobs, higher priority jobs will still start.
Child jobs like encoding now inherets the workflow priority ranging from 0 (idle) to 4 (very high). Meaning lower priority child jobs will be given less resources if higher priority jobs starts.
Starting from this version, every time you save your workflow a time stamped copy will be stored in archive for later retrieval.
All encoders now features separate audio channel mapping per track.
The AviSynth deinterlace node now includes the world renowned QTGMC deinterlacer and BWDIF.
The AviSynth resize node now includes NNEDI3 up-scaling. (Defaults to "Sinc" on down-scaling).
Several database operations speed improvements.
Slightly changed look and color scheme on nodes for improved visibility.
Selected nodes can now be connected to any node. Makes connecting several nodes easier.
Reintroduced and improved option for shutting down a complete FFAStrans farm.
Added "Clear search" and "Set max list size" in the inbuilt status monitor app.
The "A/V Media" decoder now supports forcing audio bit depth (16/24/32) and sample rate (48000/96000/192000).
"YADIF" deinterlace filter no longer force 8 bit processing on 64bit systems.
All windows now accept shortcut keys like ESC (close window), ENTER (OK) and F1 (help) where applicable.
Added option to the "Custom AviSynth script" filter to skip script verification.
The "YouTube" decoder now supports URLs as source inputs (submitted from API or the Workflow Manager).
Error state can now be forced in the "Populate variables" by populating the "%s_error%" variable.
Variables are now traversed in order to fetch variables within variables.
Added %i_v_bit_depth% for bit depth of first valid video stream.
Added option to use none linear seek in the "A/V Decoder".
The MP4 encoder now sets MPEG-4 part 14 flag as standard on mp4 files.
Fixed a bug that caused jobs to hash crash when modifying the jobs workflow.
When submitting files to host exceptioned workflows, FFAStrans could in some cases stop picking up new jobs.
FFAStrans Workflow Manager could crash when deleting nodes on very large workflows.
The GoPro monitor did not show correct progress when configured to check for growing files.
Selecting "Default" preset in nodes now properly set default node values.
Retry job did not properly re-use the stored workflow from previous job.
Fixed several issues dealing with long file paths.
Fixed a bug with "Forget missing files" monitor option not working correctly with sub-folders.
Monitors, while running, did not correctly update user variables/statics upon changes.
Fixed a memory leak in the "Insert media" filter.
Fixed a bug that caused the "Folder" delivery node to fail if output path contained some very unusual characters.
Fixed a crash when trying to browse FTP-paths.
Fixed bug that sometimes caused crash in FTP monitor.
Child processes in a job did not always close properly.
Fixed a bug that could cause monitors to go into loop when picking up very long file path.
Disabled nodes was not displayed correctly.
Pausing a job did not always cause all child processes to be suspended.
Selecting "AVI" in the uncompressed encoder did not work.
Selecting workflow properties other than the one displayed in the editor did not work.
The tray option in the Workflow Manager did not work properly.
The "Interlaced input" option in DVD encoder did not work with variables.
Fixed and removed some unneeded excessive logging in the API and queue manager.
+ Lots of other minor changes, improvements and bug fixes.
